LM3248TME/NOPB datasheet by Texas Instruments

LM3248TME/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LM3248TME/NOPB to minimize EMI and noise?
  A good PCB layout practice is to keep the input and output traces separate, use a solid ground plane, and place the device close to the power supply. Additionally, use a ferrite bead or a common-mode choke to filter out high-frequency noise.
• How do I ensure the LM3248TME/NOPB is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the input and output pins with capacitors, use a low-ESR output capacitor, and avoid using long traces or wires that can cause oscillations. Also, ensure the device is operated within its recommended operating conditions.
• What is the maximum output current of the LM3248TME/NOPB, and how do I calculate it?
  The maximum output current of the LM3248TME/NOPB is 1.5A. To calculate the maximum output current, use the formula: Iout = (Vin - Vout) / Rload, where Vin is the input voltage, Vout is the output voltage, and Rload is the load resistance.
• How do I protect the LM3248TME/NOPB from overvoltage and undervoltage conditions?
  Use a voltage supervisor or a voltage monitor IC to detect overvoltage and undervoltage conditions. You can also add a voltage clamp or a TVS diode to protect the device from voltage transients.
• What is the thermal derating of the LM3248TME/NOPB, and how do I calculate it?
  The thermal derating of the LM3248TME/NOPB is 12.5mW/°C. To calculate the thermal derating, use the formula: Pd = (Tj - Ta) / θja, where Pd is the power dissipation, Tj is the junction temperature, Ta is the ambient temperature, and θja is the thermal resistance.
